8 Claims.

This invention relates to a wall assembly and to a stud forthe use therein.

Walls-including partitions and ceilings, assembled from prefabricated units are in wide use. An especially desirable assembly is one containing studs, this term including beams, having thin faces provided with slots, preformed panels of facing or finishing material, and fastening means engaged, at one end,-in the said panels and, at another portion, engaged behind the material forming the edges of the said slots. Since the fastening means in such an assembly are concealed from view from a forward position, there has been difficulty heretofore in quick1y disengaging the fastening means and removing a panel of facing materiaLby an operator on the exposed side or face of the wall.

' It is an object of the present invention to over- I come this diiiiculty and provide an assembly or stud for use therein having means to facilitate the removal of a panel from position.

In the preferred embodiment, the invention comprises not only the wall assembly described.

but also a stud having a face provided with a slot and having means associated with a portion of the said slot for causing certain disengagement of the fastening means, when the fastening means are brought into the said portion of the slot; The

preferred embodiment is illustrated in the drawing and will be described in connection therewith.

Fig. 1; shows a perspective view from a rearward position of a wall assembly in which one of the two panels shown is in the disengaged position with respect to the stud.

Fig. 2 shows a similar view in which both the Fig. 3. shows a sectional view on line 3-3.01' Fig. 1.

There is shown a stud constituting a part of a supporting substructure and having a thin face portion I provided with a plurality of spaced slots extending lengthwise oi the face and each having portions adapted, respectively, tofacilitate disengagement or engagement of an element of the selected fastening means. Thus the slots are each provided, suitably, with a wide portion 2 and a narrow portion 3.

Satisfactory studs are'formed metal sections of the shape of channels, I-studs, or the like.

The panels I of facing material may be of seand cement boards. Y

The panels are held to the studs by the fastening means, including a portion 5 engaging a panel, a stem portion extending through one'of the said as, for example, hard asbestos wide portion of the slot. If, however, no special precautions are taken, the element 6 may be not centered in the wide portion and may become engaged behind an edge thereof, causing confusion and delay.

To overcome this dimculty, the edge of the wide or disengaging portion of the slot is provided with means to prevent movement or engagement of the element 6 therebehind, as with the shoulder t struck out from the material constituting the edge of the said wide portion.

Suitably, this shoulder slopes downwardly, to the rear, towards a line passing through thecenter of the said wide portion, so that the element 6, as forced thereagainst, maybe displaced in a forwardly direction, causing the panel 4 to become loosened from the wall. The slopes of the members 6 and 8 may be approximately parallel,

to facilitate further the disengagement described.

It will be noted that the width of the edge of the wide portion of the slot, including the means such as the shoulder associated therewith, is greater than the distance between the washer portion of the element 6, when in disengaged position, and the panel 4, so that the edge of the wide portion cannot become engaged in the space between the element 6 and the member 4.

As illustrated, means I may be a coil spring. It will be noted, also, that the fastening means may include a bolt having an end engaged in a bushing of the expanding nut typeset in the panel 4, a stem portion extending through theslot and through the element 6, if used, and a head portion 9 forming the rearof the bolt. If the element 8 is not used, the head 9 becomes the element engaged behind the face of the stud. Suitably, the element Ii is in the'form of a washer with side edges of substantial thickness and slope, as illustrated.

4 from the element 6, when the element is brought into the wide portion 01' one of the said slots, and thus decreases the width oi! the shoulder 8 required.

50 The spring 1 decreases the spacing of the panel While the function of the wide portion of the slot, and the limiting means associated therewith, has been described in connection with the disassembling of a wall, there is also an advantage in the making of the assembly initially.

Thus, when the fastening means, including the element I, are inserted into the wide portion of the slot, the limiting means 3 prevent engagement of the element 6 until such time as the element i is forced downwardly into the narrower portion of the slot, which the said element is intended to engage.

It should be understood that the details given are for the purpose of illustration, not restriction. and that variations within the spirit of the invention are to be included in the scope of the appended claims.

What I claim is:

1. In combination, a wall assembly comprising a stud, a thin face thereof provided with a slot of varying width, a panel of facing material, fastening means holding the panel to the stud and including a portion engaging the panel, a.

stem portion extending through the slot, an element engaged behind the edge of the slot, a wide portion of the slot adapted to facilitatedisengagement of the said element, and means associated with the material forming the edge of the said wide portion for limiting the movement of the said element and preventing the engagement thereof behind the edge of the said wide portion. s

2. In combination, a wall assembly comprising a stud, a thinface thereof provided with a slot of varying width, a panel of facing material. fastening means holding the panel to the stud and including a portion engaging the panel, a stem portion extending through the slot, an element engaged behind the edge of the slot, 8. wide portion of the slot adapted to facilitate disengagement of the said element, and means including a shoulder struck out from the mate rial forming the edge of the said wide portion and limiting the movement of the said element and preventing the engagement thereof behind the edge of the said wide portion, the said shoulder sloping, to the rearward, towards a line extending through the center of the said wide portion.

3. In combination, a wall assembly comprising a stud, a thin face thereof provided with a slot of varying width, 9. panel of facing material, fastening means holding the panel to the stud and including a portion engaging the panel, a stern portion extending through the slot, an element engaged behind the edge of the slot, a wide portion of the slot adapted to facilitate disengagement of the said element, and means including a shoulder struck out from the material forming the edge of the said wide portion and limiting the movement of the said element and preventing the engagement thereof behind the edge or the said wide portion, the said element sloping to aceaaee the rearward and towards a line passing through the center of the said stem portion of the fastening means extending through the slot, the said shoulder and sloping element facilitating separation of the panel from the stud when the said element is forced in the direction 'of the wide portion of the slot and against the shoulder.

4. In combination, a wall assembly comprising a stud, a thin face thereof provided with a slot of varying width, a panel of facing material, fastening means holding the panel to the stud and including a portion engaging the panel, a stern portion extending through the slot, an element engaged behind the edge of the slot, a wide portion of the slot adapted to facilitate disengagement of the said element, means associated with the material forming the edge of the said wide portion for limiting the movement of the said element and preventing the engagement thereof behind the edge of the said wide portion, and spring means acting upon the said element and forcing .the element towards the panel when the element is brought into the said wide portion of the slot.

5. A stud, adapted for use in a wall assembly including fastening means and being of the class described, comprising a formed metal member, a thin face thereof provided with a slot having a wide portion and a narrower portion, and means associated with the material forming the edge of the said wide portion and adapted to limit movement and prevent engagement therebehind of the said fastening means.
